Nothing wrong with life’s little wakeup calls unless, of course, you almost sleep through one of them.

And the Boston Bruins know all about that.

As much as the Detroit Red Wings pose an intriguing threat in this Eastern Conference No. 1 vs. No. 8 matchup beginning here on Friday night at the TD Garden, the Bruins hope they have learned their lesson from first-round scares.

The long, storied history of the Stanley Cup playoffs added one of its most memorable (and improbable) chapters at that very same rink last May 13 when the Bruins overcame a 4-1 third-period deficit and stunned the Maple Leafs in overtime of Game 7.

Toronto, it would seem, never recovered from the debacle after a far more sustained collapse kept them from playoff hockey this spring. The Bruins? Well, they’re poised to launch what they hope will be a third trip to the Stanley Cup final in the past four seasons.
